Same thing happens to me with Dell Optiplex G240(a Desktop, though).
When it's running FreeBSD-stable, the cooling fan is very calm, while with
DragonFly the fan keeps turning noisily as if it's running buildworld.
I haven't tried recent acpi code from FreeBSD-CURRENT, but it doesn't seem
to have any CPU throttling feature.
I tried older DragonFly kernel/world, and found that DragonFly from
source as of 2003.09.01.00.00.00 already exhibits this symptom. I
also wanted to try 2003.08.01.00.00.00 and 2003.07.20.00.00.00, but
somehow both didn't compile.
